Simulation method of multi-axis electrically-propelled semi-physical simulation test platform

Abstract

The invention belongs to the field of ship simulation experiment platforms and discloses a simulation method of a multi-axis electrically-propelled semi-physical simulation test platform. The method includes: (a) acquiring the actual operational data of a ship to build a mathematical model and verifying and adjusting the model; (b) presetting ship speed, using a simulation model to calculate the expected value of a motor unit parameter, and transmitting the expected value to a simulator; (c) enabling the real-time simulator to receive a command and to adjust the motor unit to operate accordingto the expected value, enabling the motor unit to feed back an actual value signal to the real-time simulator and to an input module, enabling the input module to compile the actual value signal intoCPU-identifiable information, and using the simulation model to calculate the required ship speed, thereby realizing the closed-loop control of the motor unit parameter and completing the simulationprocess. The method avoids inaccuracy of the simulation model caused by all-digital simulation, achieves high similarity with a real test environment, fast hardware response, high real-time performance, and high economic efficiency, and provides guidance for practical research.

Description

technical field [0001] The invention belongs to the field of ship simulation experiment platform, and more specifically relates to a simulation method of a multi-axis electric propulsion semi-physical simulation experiment platform. Background technique [0002] The increasingly fierce market competition has put forward higher requirements and challenges for the time to market of products and the speed of new product development. At the same time, the requirements for product reliability and stability are also increasing. At present, the design methods of many control systems and electronic systems are still completely based on the development process of software simulation. Since the development process only realizes the verification of the system structure, principle and algorithm, it is difficult to guarantee the performance of the final prototype hardware system. On the one hand, the hardware part of the system has not been implemented. Simulation testing, on the other h...
